work support. The copy holder comprehends a line guide mechanism thatincludes a line. guide bar. The line guide mechanism is constructed sothat the line guidebarthereof is positionable vertically along the frontof and in respect to a plate of the worklholder in front of which platethe sheetsfare supported and in Fig. 9 the parts of'this line guidemechanism are shown in one of the positions wherein the line guide barthereof occupies a relatively high position while'in Figs. 1, {L and 5the parts of theline guide mechanism are shown in a position whereinthe-line guide bar occupies a relatively low one side of supporting bar3 as is clearly seen from Figure 1 in conjunction with Figure 4, to andprojecting forwardly from the base bar 1 are twoclamps 7 whichare-adapted to clamp upon the rear bar f the typewriting machine 5. Eachof these clamps 7 comprises what may be termed the main or fixed jaw '7and the movable jaw 7", as is clearly shown in Fig. 1. In this way, thecopy holder may be secured in fixed relation to thet-ypewriting machineat the rear of the latter.

The base frame also-comprises two rodson guides9 projecting upwardly inparallel relation from the base bar 1. On this base frame is verticallymovable an upper frame comprising, in'this instance, a plate 10 have ingsemi-circular guides 11 at opposite vertical edges rolled rearwardlyfrom the metal of which the plate 10 is formed and engaging'theouterfaces of the guide bars 9 while leavingtheir' inner faces exposed. Thelower edge of the plate is turned rearwardly at 12 to strengthen theplate. lViththe end in view of holding the upper frame in. raisedposition on the base or lower withdrawal 'of the upper frame from thelower frame the upper frame carries two detents 12 which are pivoted at13 on the rear side of the plate and have each two detaining portions 14and 15. The detaining portion 14 of each detent is in the form of ashoulder 16 adapted to enter a notch 17 in the adjacent rod 9 to engageashoulder 18 at the top of the notch to limit the upward move ment ofthe upper frame on the base frame. The detaining portion carries aroller 19 at its free end to engage the upper end of the adjacent rod 9.Each rod has a beveled portion 20 over which the roller 19 travels.lVhen theupper frame is in its upper position the projecting shoulder 16of each detent lies in a notch 17 and the roller 19 engages the upperend of the adjacent rod. The two detents are connected below theirpivots by a single coil spring 21 which holds the de tents toward theguide rods 9 and causes the detents to sustain the upper frame in itsraised position by engaging the upper ends of the rods 9. To lower theupper frame on the base frame, the upper frame is pushed downwardl vwith pressure so that the rollers 19 ride onto the beveled portions 20which shift the detents on their pivots to tension the spri g 21, andshift the portions 14 out of the notches 17, after which the rollers 19ride down the rods 9 holding the detents against action until the upperframe is again moved to its uppermost position.

' The upper portion of the plate 10 is provided with a stiffening orreinforcing plate 10, the upper edge of which is deflected rearwardlyatan incline at 22 and the matter 'to be copied is turned over this edgeand is clamped to said inclined edge portion 22 of the stiffening plate10*. When a stenographers notebook 23 is to be copied, the back and anynumber of pages are turned so as to have a position behind the rear faceof the plate 10 and 10. the binding23 being situated at the deflectedportion 22. The clamping of these turned pages may be effected by aclamp comprising. in this instance, an inverted U shaped swinging member24, the arms of which are pivoted at 25 to the rear face of the upperframe member. Springs 26 act on this clamp to hold the horizontalportion toward the upper edge of the rearwardly inclined portion so thatsaid ed e assists in the clamping action and forms a clamping member.Finger pieces 27 may be provided at the ends of the arms to providemeans through which 7 the'clamp may be manipulated.

Associated with the upper work holding frame is a line guide past whichthe work is moved by a means such as that hereinafter described. Thisline guide comprises, in this instance, a rocking bar 28 mounted infriction bearings 29 on the rear face of the upper frame and having tworigid arms 30 at its opposite ends. Adjustable on said arms 30 are thearms 31 of a swinging U shaped member the connecting portion 32 of whichhas a guide plate 33 mounted to swing with friction thereon.

There may be associated with the line guide, a sheet guiding meanswhich, in this instance, comprises two guides 34 projecting rearwardlyfrom the rear face of the line guide and adjustable relatively to eachother in the direction of the length of the line guide. In thisinstance, each sheet guide 34 has guide flanges 35 frictionallyembracing the upper and the lower edge of the line guide so that theguides may be shifted to engage opposite side edges of the book leavesin front f the work holding frame. These guides cause the leaves totravel in straight lines past the line guide under the action of thesheet feeding means.

, The sheet feeding means comprises, in this instance, a plurality ofaxially alined feed rollers 36 arranged. on a shaft 37 so as tocooperate with theuppermost sheet at the front of the work supportingframe and directly in front of the rearwaardly deflected portion 22slightly below the binding 23. The feed roller shaft 37 is" supported tomove toward and from the work support and is held with yielding pressuretoward the work. In this instance, the shaft 37 is supported byaswinging frame having a horizontal connecting portion 38 and twodepending arms 39 which are pivoted at 40 to two-arms 41 extendedforwardly from the ends of a bar 42 secured to the rear face of the worksupporting frame as is clearly shown in Figs. 1 and 4. A stop 43 atthelower end of one of these arms serves to limit the outward movement ofthe swinging frame and the pivots 40 are arranged in advance of the feedshaft 37 so that the weight of the swinging frame and the parts carriedthereby hold the rollers 36 with yielding pressure toward the work.Springs 44 may connect the arms 41 with the arms 39 to still furtherinsure the feed rollers being held toward the sheets to be fed,adjusting devices 45 being provided to vary the tension of the springs.The position of the springs 44 from one point of view in reference tothe bar 42 and the swinging arms 39 is clearly indicated in Fig. 5,while the position of the springs 44 from another point of view inreference to the bar and swinging arms is illustrated in Fig. 1, whereinthe adjusting means 45 is also clearly shown.

The shaft 37 carrying the alined feed rollers 36 has a step by step feedimparted thereto through the medium of step by step feeding mechanismcomprising a clutch member in the form of a cup, including an annularflange 46, and has a bushing 48 rigidly secured thereto centrallythereof. This bushing embraces one end of the shaft 37 and is ifs latethereon. at 46* to the outer end of the aforesaid arm may be termedkeyed to said shaft by means of a screw or edge of the flange ofthecup'and an arm is loosely mounted on said bushing to oscil- A curvedarm 46 is pivoted .the inner'surface of the flange of the cup whereby toellect an alternate gripping and releasing dri'ving connection between.said lug onshoe's and-the interior of theannul-ar flange 46 ofthe cup.

It will be seen from the foregoing that the cup shaped clutchine-mberthat includes the annular flange 46 and the curved arm l6 whichprovides the shoe'or lug 46 cooperate and provide'w'hat the frictionmembers or elements of a step by step feedingclutch. his alternategripping and releasing action is. effected in any suitable manner, oneway being to connect a flexible pull wire with one end of the saidcurved arm 46 and which wire extends through a'flexible'sheath' 56connected at 57to member39 and having its out.- er end extending intothe s box 59 where it is attached at'5S.

A spring 52"acts on the arm 50 to return saidarm normally to startingposition, the rear end of the curved arm 46 engaging the stop 53 toarrestthe return movement of both arms 46 and 50 at starting position.By virtue of this particular character of clutch mechanism it ispossible to turn the shaftin-either direction in the operation of thecopy holder, thatis to say, by the operating of the. clutch mechanismthe step by step feed of therollers in a forward direction is enabledto'be carried out as and when desired or by means of the knob-or fingeropera ed wheel 79, herinafter more fully referred tmthe feed rollers canbe turned forwarcly freely or rearwardly against the friction holding ordriving engagement of the clutch construction, whichnormally tenos toprevent er op pose such rearwardturnin movement;

Mechanism fore *ating the curved arm l6 and thereby the clutch mechanismisconr prehended within or is arried by a box 59 clearly shown in Fi 2and 3. The operating mechanism and the box 59 therefor is arrangedconveniently in respect tothe keyboard of the typewriting machine andhimcured in place at theright front side of the typewriting machine isclearly shown in Figs. 1 and 3.

The box 59 forms a support for the wire or cable operating means and tothis end is formed of two partsproviding a chamber 60 between them. Inthis" chamber is mounted a bell crank lever 61 having one arm connectedto the lowerend of the pull. wire. The other arm has a pin and slotconnection 62 withv a finger lever fi w-hichis pivoted at G L'tO'thezcasing. spring 65 actson the pin 'ofthe ointbetweenitheftwoileversand-returns the pull. wire to normal position after each depressioniofithefingerlever '63.

The box 59hasa thin lateral.support 59 0n=its innerside' sothat the forward foot of a'typewr-itingmachine may rest thereon. At the same time the b0 59 is clamped to thetypewriting machine by a clamp comprising, in this instance, aborizontallug 67 having avertical slot 68 andlproiectedfrom a forward extension 69on the frame. The side frame of the'typewriting machine 5 rests againstone face of this eX- tension while a set screw 70 en 'a 'es the oppositeface and is-mounted in one arm of a substantially 'UVshaped-clamp 71which is loosely fulcrumed in the :lug 67. Said clamp has a grippingportion 72 on the other arm to drawthe frame 59 against the frame of thetypewriting machine. Between its ends the-sheathfiti is slidable in aloop 73 onanarm 75 supported fromthe base frame;

In order to enclosethe feeding mechanism, a" hood 76 is supported by theswinging frame 38l39 and extends above and below the hori: zontalportion 38 of. the frame, The upper portion of the hoodextendsrearwardly and.
